“Between 2007 and 2014, when Pew conducted two
major surveys of U.S. religious life, Americans who described themselves as
atheist, agnostic or of no particular faith grew from 16 percent to nearly 23
percent. At the same time, Christians dropped from about 78 percent to just
under 71 percent of the population. Protestants now comprise 46.5 percent of
what was once a predominantly Protestant country.”
